(1956, Nigel Stock, Muriel Pavlow, Michael Craig, Donald Sinden)

A London trolleybus is glimpsed on route 667:

Muriel Pavlow's character is knocked down by London Transport RT4566 (NXP858) on fictional route 534 to 'Barlow Station':


A second unidentified RT (appears to be another NXPxxx registration) passes the accident with similar destination.
